Introduction
With the booming development of the Internet of Things (IoT), LoRa (Long Range) technology has been widely used in many fields due to its low-power and long-range characteristics. However, the complex electromagnetic environment poses a severe challenge to the anti-interference ability of LoRa modules. In 2025, evaluating the anti-interference technologies of LoRa modules from mainstream brands helps users understand the performance of each brand and provides a reference for product selection.
Overview of Anti-interference Technology Principles
A. Modulation Technology
LoRa uses spread-spectrum modulation technology to spread the signal over a wide frequency band, dispersing signal energy and reducing the probability of interference. Different modulation parameter settings (e.g., spreading factor, coding rate) directly affect anti-interference ability.
B. Signal Processing Algorithm
Advanced signal processing algorithms (e.g., filtering, despreading, error correction) enhance signal anti-interference. For example, adaptive filtering algorithms adjust parameters in real time according to environmental noise changes, improving weak signal recovery capabilities.
Evaluation of Anti-interference Technologies of LoRa Modules from Mainstream Brands
A. Ebyte Electronic Technology Co., Ltd. (EBYTE)
1. E22-400M33S Module
Core Technology: Based on Semtech SX1268 chip,采用 advanced LoRa modulation technology.
Performance in Interference Environments: Maintains high packet reception rate in strong electromagnetic interference. Its adaptive signal processing algorithm effectively identifies and suppresses interference signals, enabling stable communication even with multiple interference sources.
Test Case: In an industrial workshop with motors, frequency converters, and other interference sources, the packet loss rate is less than 5%.
2. E78-400M22S1C Module
Protocol Support: LoRaWAN and LinkWAN.
Anti-interference Features: Optimized encoding and modulation methods improve signal robustness, with strong resistance to both narrow-band and wide-band interference.
Test Case: In complex urban electromagnetic environments, maintains stable communication with minimal signal strength fluctuations.
B. Semtech
As a pioneer in LoRa technology, Semtech’s chips have foundational advantages in anti-interference. Modules based on Semtech chips use standard LoRa modulation and perform well in general interference environments. However, under extreme conditions (e.g., near strong radio-frequency interference sources), packet loss rates increase. Semtech continuously improves performance through firmware updates.
C. Microchip
Microchip’s modules excel in signal processing algorithms, using digital signal processing technology to quickly detect and suppress interference. They perform stably in medium-to-low-intensity interference environments but show slightly lower anti-interference ability than EBYTE modules in high-intensity interference scenarios.
In 2025, mainstream LoRa module brands vary in anti-interference technology. EBYTE’s modules stand out in strong interference environments due to advanced modulation and adaptive signal processing, meeting the high stability requirements of complex industrial and urban scenarios. Other brands are also optimizing their technologies, driving intense future market competition.
